Detailed Description

Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.

The following disclosure provides many different embodiments, or examples, for implementing different features of the disclosure. To simplify the disclosure of the present disclosure, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present disclosure. Further, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

With the popularization of electronic devices, such as mobile phones, due to falling, etc., screens, glass rear covers, etc. of the devices are often broken. The data show that the impact damage is the largest factor causing the repair of the electronic equipment, which brings great economic loss to users and causes use troubles and use concerns to the users. In order to solve at least one of the above technical problems, the present disclosure proposes a fall-prevention assembly 100, an electronic device 1000 having the same, and a protective case 2000 of the electronic device 1000.

Hereinafter, a fall arrest assembly 100 according to an embodiment of the first aspect of the present disclosure is described with reference to the accompanying drawings.

As shown in fig. 1, the drop-preventing assembly 100 includes a receiving member 1 and an ejecting mechanism 2, the ejecting mechanism 2 includes an ejector 21, a guide post 22 and a driving member 23, and the ejector 21 is disposed at an outer end 22a of the guide post 22. The connection mode of the ejector 21 and the guide post 22 is not limited, and may be fixed and connected through an assembling process or may be an integrally molded component. In addition, the material of the pop-up member 21 is not limited, and may be, for example, an elastic material, so as to improve the protection effect, and for example, the material of the pop-up member 21 may also be specifically set according to the application scenario of the anti-falling component 100, for example, when the anti-falling component 100 is applied to the electronic device 1000 whose outer side frame is a metal member, the pop-up member 21 may also be a metal material, so that the pop-up member 21 may be well integrated into the application scenario.

Referring to fig. 2, the receiving member 1 defines a guide channel 101, and the guide post 22 is engaged with the guide channel 101, that is, at least a portion of the guide post 22 is located in the guide channel 101 to be slidable along the guide channel 101. The cross-sectional shapes of the guide post 22 and the guide channel 101 are not limited, as long as the guide channel 101 can restrict the guide post 22 from moving substantially smoothly, so that the ejector 21 ejects substantially smoothly. For example, in some specific examples, the guide channel 101 may be cylindrical, and the guide post 22 may be cylindrical, so that the guide post 22 may be in clearance fit with the guide channel 101, so that the guide post 22 may move smoothly along the guide channel 101.

As shown in fig. 3 and 4, the eject mechanism 2 is switchable between an eject state and a storage state, and the driving member 23 is used for driving the guide post 22 to slide outwards along the guide channel 101 so as to switch the eject mechanism 2 from the storage state to the eject state. For example, as shown in fig. 3, when the eject mechanism 2 is switched to the storage state, both the outer end 22a and the inner end 22b of the guide post 22 are located in the storage member 1, and as shown in fig. 4, when the eject mechanism 2 is switched to the eject state, the inner end 22b of the guide post 22 is located in the storage member 1, the outer end 22a of the guide post 22 moves out of the guide passage 101 to push the eject piece 21 out of the storage member 1, and at this time, the eject piece 21 is in a protruding state to preferentially contact with the ground or the like, thereby effectively protecting the electronic device 1000 or the like to which the drop-preventing assembly 100 is applied.

From this, according to prevent falling subassembly 100 of this disclosed embodiment, through setting up guide channel 101 and guide post 22 cooperation to make pop-up piece 21 can pop out smoothly, with the popped-up reliability and the smoothness that improve pop-up piece 21, avoid the popped-up card of pop-up piece 21 to die the problem, and then improve the protection reliability of preventing falling subassembly 100.

According to the anti-falling assembly 100 of some embodiments of the present disclosure, as shown in fig. 2, the guide post 22 is in guiding fit with the guide channel 101 through the guide structure 4, so that the guide post 22 is limited by the guide structure 4 to move along the axis of the guide post 22 relative to the guide channel 101, and it should be noted that the axis of the guide post 22 described herein refers to the central axis of the guide post 22. Therefore, the ejection reliability and the smoothness of the ejection member 21 can be further improved, the problem of the ejection locking of the ejection member 21 can be further avoided, and the protection reliability of the anti-falling component 100 can be further improved. Moreover, since the guide post 22 only moves in the axial direction, the space required for the movement of the guide post 22 can be reduced, and the overall compactness of the anti-falling assembly 100 can be improved, so that the anti-falling assembly can be better applied to small-sized devices and has a wide application range.

For example, in the specific example shown in fig. 2, the guide structure 4 may comprise: the guide structure comprises a guide convex rib 221 and a guide groove hole 102, wherein the guide convex rib 221 is formed on the outer circumferential surface of the guide column 22 and extends from the outer end 22a of the guide column 22 to the inner end 22b of the guide column 22, the guide groove hole 102 is formed on the guide channel 101 and is positioned at the inner end 101a of the guide channel 101, and the guide groove hole 102 is matched with the guide convex rib 221, so that the guide column 22 can move along the axis of the guide column 22 due to the matching of the guide convex rib 221 and the guide groove hole 102 in the moving-out process of the guide column 22. The guide structure 4 is thus simple in construction, easy to machine, and can simply and effectively ensure that the guide post 22 moves along its own axis.

The guide rib 221 may extend along a straight line, may extend along a curved line, or may extend along a combination of a straight line and a curved line, and may be specifically set according to different requirements. Therefore, the motion form of the guide post 22 can be changed by adjusting the extending shape of the guide rib 221, for example, when the guide rib 221 extends along a straight line parallel to the axis of the guide post 22 (for example, the first straight line segment 22c and the second straight line segment 22e described later), the guide post 22 can be made to move along the axis of the guide post 22, and when the guide rib 221 extends along the circumferential direction and the axial direction of the guide post 22 synchronously to form a curved rib (for example, the curved line segment 22d described later) winding the guide post 22, the guide post 22 can be made to rotate around the axis of the guide post 22 while moving along the axis of the guide post 22, so that different practical requirements can be met

Note that the term "inner" as used herein refers to a side of the guide post 22 that moves in a direction to switch the eject mechanism 2 to the stored state, and the term "outer" as used herein refers to a side of the guide post 22 that moves in a direction to switch the eject mechanism 2 to the ejected state.

In some embodiments of the present disclosure, as shown in fig. 3 and 4, the guide structure 4 may be configured to drive the guide post 22 at least one segment of the overall movement along the axis of the guide post 22, with the guide post 22 rotating about the axis of the guide post 22. That is to say, in the process that the guiding column 22 moves outwards along the guiding channel 101, the guiding column 22 moves along the axis of the guiding column 22 and rotates around the axis of the guiding column 22 in at least one stage, so that the ejecting member 21 rotates in at least one stage, and the ejecting member 21 presents a certain angle after being ejected, thereby playing a better protection role and further avoiding the problem that the electronic device 1000 applied to the ejecting member 21 contacts with the ground when falling.

For example, in the specific example shown in fig. 3 and 4, the guide structure 4 may be configured such that the entire process of driving the guide post 22 to move along the axis of the guide post 22 includes a front stage process in which the guide post 22 does not rotate around the axis of the guide post 22 at all times, a rear stage process in which the guide post 22 rotates around the axis of the guide post 22, and a rear stage process in which the guide post 22 does not rotate around the axis of the guide post 22 at all times. Thus, in the process of the guide post 22 moving outward along the guide channel 101, the ejector 21 does not rotate in the front section process, the ejector 21 rotates in the rear section process, and the ejector 21 does not rotate in the rear section process, or the ejector 21 does not rotate when it starts to eject, and rotates at the rear and finally does not rotate. From this, convenient processing makes pop-up member 21 can play better guard action moreover, further avoids the electronic equipment 1000 that pop-up member 21 used to take place surface and ground contact problem when falling.

Further, in order to ensure the above movement, the guide rib 221 may include a first straight line segment 22c extending linearly inward from the outer end 22a of the guide post 22, a second straight line segment 22e extending linearly outward from the inner end 22b of the guide post 22, and a curved line segment 22d extending rotatably from the inner end of the first straight line segment 22c to the outer end of the second straight line segment 22e, the first straight line segment 22c and the second straight line segment 22e being parallel to the axis of the guide post 22 and being spaced apart in the circumferential direction of the guide post 22, the first straight line segment 22c engaging with the guide slot 102 so that the guide post 22 does not rotate about the axis of the guide post 22 during the front section, the curved line segment 22d engaging with the guide slot 102 so that the guide post 22 rotates about the axis of the guide post 22 during the rear section, and the second straight line segment 22e engaging with the guide slot 102 so that the guide post 22 stays during the rear section.

That is to say, when the first straight line segment 22c is matched with the guide slot 102, the guide post 22 can simply move along the axis of the guide post 22 without rotating, and when the curved line segment 22d is matched with the guide slot 102, the guide post 22 can move along the axis of the guide post 22 in a rotating manner, so that the movement requirement of the guide post 22 can be met, and after the movement of the guide post 22 is finished, the reliability of the ejection piece 21 staying at the ejection position can be improved by means of the matching of the second straight line segment 22e and the guide slot 102, the problem of retraction of the ejection piece 21 is improved, and the protection effect is improved.

As shown in fig. 2, the two guide ribs 221 configured as above may be symmetrically disposed about the axis center of the guide post 22, and the two guide slots 102 are correspondingly engaged with the two guide ribs 221. This can further improve the ejection smoothness of the ejector 21. In addition, as shown in fig. 2, in this embodiment, the guide structure 4 may further include two auxiliary ribs 222 extending along a straight line, and the auxiliary ribs 222 extend parallel to the axis of the guide post 22, with reference to fig. 5, the two auxiliary ribs 222 and the two first straight line segments 22c are alternately and uniformly spaced apart along the circumferential direction of the guide post 22, that is, each auxiliary rib 222 is located at an intermediate position between the two first straight line segments 22c, and in the axial direction of the guide post 22, the auxiliary ribs 222 are located at the same position as the first straight line segments 22c, and the guide structure 4 further includes two auxiliary slots 103 respectively corresponding to the two auxiliary ribs 222, that is, each auxiliary rib 222 is correspondingly matched with one auxiliary slot 103 respectively. Therefore, the two guide ribs 221 and the two auxiliary ribs 222 can form a cross rib, and the two guide slots 102 and the two auxiliary slots 103 can form a cross slot, so that the ejection stability of the ejection member 21 can be further improved.

In addition, in some embodiments of the present disclosure, the angle through which the guide post 22 rotates around the axis of the guide post 22 is 80 ° to 100 ° throughout the switching of the eject mechanism 2 from the storage state to the eject state. For example, the guide post 22 may be rotated through an angle of 80 °, 90 °, 100 °, etc. about the axis of the guide post 22. This can provide a more effective protective effect and also make the structure of the guide post 22 simpler. Of course, the present disclosure is not limited thereto, and the angle through which the guide post 22 rotates around the axis of the guide post 22 may also be less than 80 °, or greater than 100 °, etc., such as 60 °, 70 °, 110 °, 120 °, etc., throughout the switching of the eject mechanism 2 from the storage state to the eject state.

Further, when the angle through which the guide post 22 is turned around the axis of the guide post 22 is 90 °, for each guide bead 221, the first straight line segment 22c and the second straight line segment 22e may be separated by an angle of 90 ° in the circumferential direction of the guide post 22, that is, an angle between a plane defined by the center line of the first straight line segment 22c and the axis of the guide post 22 and a plane defined by the center line of the second straight line segment 22e and the axis of the guide post 22 is 90 °, so that the turning angle requirement of the guide post 22 can be simply and effectively satisfied.

In other embodiments of the present disclosure, as shown in fig. 6, the guide structure 4 may be configured such that the guide post 22 does not rotate about the axis of the guide post 22 at all times during the movement of the guide post 22 along the axis of the guide post 22. Therefore, the ejector 21 is not rotated all the time during the outward movement of the guide post 22 along the guide passage 101, so that the structure can be simplified and the ejection speed of the ejector 21 can be increased. Further, in order to ensure the above movement, the guide rib 221 may be configured to extend all the way along a straight line parallel to the axis of the guide post 22 from the outer end 22a of the guide post 22 to the inner end 22b of the guide post 22, thereby facilitating the processing and satisfying the moving requirements of the guide post 22. In addition, the number of the guide ribs 221 is not limited, and may be one or more, for example, in the example shown in fig. 6, the guide ribs 221 may be four and are uniformly distributed as cross ribs along the circumferential direction of the guide column 22, in this case, the guide slot hole 102 may be four cross holes correspondingly, so as to be correspondingly matched with the four guide ribs 221 respectively.

In some embodiments of the present disclosure, as shown in fig. 2 and 3, the driving member 23 may be a driving spring 231, the driving spring 231 is fitted in the guiding channel 101 and sleeved outside the guiding post 22, an outer end 231a of the driving spring 231 is connected to the ejecting member 21, and an inner end 231b of the driving spring 231 is connected to the inner end 101a of the guiding channel 101. Therefore, after the guide post 22 is released, the driving spring 231 can restore to deform to extend, the ejection piece 21 is driven to eject in the process that the driving spring 231 extends, the guide post 22 is driven to move outwards in the process that the ejection piece 21 ejects, and the guide post 22 and the guide channel 101 are matched to move along the guide channel 101, so that the ejection smoothness and reliability of the ejection piece 21 can be improved. Of course, the present disclosure is not limited thereto, and the driving spring 231 may be replaced by other means such as a driving cylinder, an electromagnet, and the like.

The drop-preventing assembly 100 according to some embodiments of the present disclosure may further include a locking mechanism 3, as shown in fig. 3 and 4, the locking mechanism 3 is housed in the housing member 1, the locking mechanism 3 is switchable between a locked state and an unlocked state, the locking mechanism 3 is interlocked with the ejection mechanism 2, as shown in fig. 3, when the locking mechanism 3 is switched to the locked state, the ejection mechanism 2 is locked in the housed state, as shown in fig. 4, when the locking mechanism 3 is switched to the unlocked state, the ejection mechanism 2 may be switched from the housed state to the ejected state. Thus, according to the drop-prevention assembly 100 of the embodiment of the present disclosure, the operational reliability of the eject mechanism 2 can be improved. Of course, the present disclosure is not so limited, and the locking mechanism 3 may be omitted when the driving member 23 may be autonomously controlled, for example, when the driving member 23 is a driving cylinder or an electromagnet.

In some embodiments, as shown in fig. 3, the locking mechanism 3 may include a rotating member 31, a pushing member 32 and a resetting member 33, the rotating member 31 is rotatably connected to the receiving member 1, the rotating member 31 is in locking engagement with the guide post 22 through the limiting structure 5, the pushing member 32 is configured to push the rotating member 31 to rotate so as to switch the locking mechanism 3 from the locking state to the unlocking state, and the resetting member 33 is configured to push the rotating member 31 to rotate so as to switch the locking mechanism 3 from the unlocking state to the locking state. That is, the pushing member 32 pushes the rotation member 31 to rotate in the opposite direction to the direction in which the returning member 33 pushes the rotation member 31 to rotate.

It should be noted that the pushing member 32 is suitable for being connected to a sensing device, such as an acceleration sensor, for detecting a fall of the electronic device 1000 to which the fall protection assembly 100 is applied, so that when the sensing device detects a fall risk, the pushing member 32 drives the rotating member 31 to rotate to unlock, so that the ejecting member 21 is ejected to play a protection role. Moreover, when the pop-up mechanism 2 is in the storage position, the reset piece 33 can push the rotating piece 31 to stay at the locking position, so that the locking reliability of the locking mechanism 3 for the pop-up mechanism 2 is ensured, and the pop-up mechanism 2 stably and reliably stays at the storage position when the pop-up mechanism 2 does not need to be popped up. This simplifies the structure of the lock mechanism 3 and improves the operational reliability.

For example, in the specific example shown in fig. 3, the limiting structure 5 may include: a limit groove 223 and a limit hook 311, the limit groove 223 being formed on the guide post 22, the limit hook 311 being formed on the rotation piece 31 and the locking mechanism 3 assuming a locked state when the limit hook 311 is fitted in the limit groove 223. For example, in the example shown in fig. 4, the stopper groove 223 may be an annular groove formed at the inner end 22b of the guide post 22 and extending in the circumferential direction of the guide post 22. Therefore, the limiting groove 223 is convenient to process, and no matter whether the guide post 22 rotates or not, rotates to any angle position, the limiting groove 223 can be effectively matched with the limiting hook 311 to realize locking.

For example, in the example shown in fig. 3 and 4, the rotating member 31 may include a first section 312 and a second section 313 arranged in sequence along the length direction of the rotating member 31, the rotating member 31 is rotatably connected to the receiving member 1 through a rotating shaft 6, the rotating shaft 6 is located between the first section 312 and the second section 313, the first section 312 is used for locking and cooperating with the guide post 22, the pushing member 32 and the resetting member 33 are both used for driving the second section 313 to rotate, and the pushing member 32 and the resetting member 33 are distributed on both sides of the second section 313. Therefore, the layout is reasonable, the assembly is easy, and the pushing member 32 and the returning member 33 can simply and effectively push the rotating member 31 to rotate towards the opposite direction.

Specifically, the specific selection of the pushing element 32 and the returning element 33 is not limited, for example, in some specific examples, the pushing element 32 may be an electromagnet, and the returning element 33 may be a return spring 331. This provides high operational reliability. In addition, when the reset element 33 is a reset spring 331, the receiving member 1 may have a positioning slot 114 (see fig. 1), and one end of the reset spring 331 is received in the positioning slot 114 and the other end of the reset spring is stopped against the second section 313. This can improve the positioning reliability and mounting convenience of the return spring 331. For example, in the example shown in fig. 3 and 4, the pushing member 32 may be located inside the second section 313, and the restoring member 33 may be located outside the second section 313, and at this time, the outer end of the restoring spring 331 may be fitted into the positioning groove 114. Of course, the disclosure is not limited thereto, and the return spring 331 may also be positioned in other manners, for example, a column structure may also be provided, so that the return spring 331 is sleeved on the column structure.

In some embodiments, as shown in fig. 1 and 3, the receiving member 1 may include a base portion 11 and a cover portion 12, the base portion 11 defines an inner cavity 111, an outer cavity 112 and a first passage cavity 113 communicating between the inner cavity 111 and the outer cavity 112, the cover portion 12 defines a second passage cavity 121, the cover portion 12 is detachably connected to the base portion 11, the first passage cavity 113 and the second passage cavity 121 are combined to form the guide passage 101 when the cover portion 12 is coupled to the base portion 11, the locking mechanism 3 is received in the inner cavity 111, and the ejector 21 is received in the outer cavity 112 when the ejector mechanism 2 is in the receiving state. Therefore, the accommodating component 1 is simple in structure and convenient to process, and installation of the ejection mechanism 2 and the locking mechanism 3 is facilitated. Of course, the disclosure is not limited thereto, and in other embodiments of the disclosure, the receiving member 1 may be processed into other structural forms, and the like, which are not described herein again.

Next, an electronic apparatus 1000 according to an embodiment of the second aspect of the present disclosure is described with reference to the drawings.
